In QoS, during classification, the packet must match certain parameters, right? Like if we want to prioritize HTTPS traffic, for example, it must match the port number or some other parameters.
However, after one device classifies and marks the packet, does the next device that receives the packet also need to do the same comparisions to see if the packet matches any of the configured parameters, or can it simply look at the DSCP/PCP value and deduce the classification from that?
